You cannot compare Ethereum with the two as it has huge use cases in comparison. BSV has been naturally pump and dump since its origination. Ethereum is far quality more than them at any time and the future will tell certainly that all the BCH and BSV will not last and withstand the test of time and they are just fork of Bitcore core
In general, you are right, it is difficult to compare here, but technically we can do it. It all depends on which person needs the result, or rather, at what distance.
This may be a short term goal or a long term one. It is obvious that Ethereum wins on profits in the long run, because the growth of BSV is associated exclusively with speculation.
